More particularly, the site is located at 1500 Aberdeen Avenue N.E., Renton, Washington. The site currently exists as an existing single-family residence located on a 0.39-acre lot,with an associated pool in the backyard, concrete driveway, and several trees scattered through the backyard of the lot. The proposal for this development is to construct a 3-lot short plat by adding two new lots to the development behind the existing single-family residence located in the front portion of the lot. The majority of the lot, from the approximate location of the existing house,slopes off toward the back of the lot in an easterly direction at an approximate grade of 1 1/2 percent. The front yard of the lot slopes off toward Aberdeen Avenue N.E. at a similar grade. The existing trees on the lot are fir trees and,for the most part,will be cut down for development of the short plat. The project site soils are classified as Indianola, which is a Type "A" soil, meaning infiltration would be applicable if it was required from this development. • • 7585.005[DED/bq/knl 1.1 Technical Information Report Worksheet King County Department of Development and Environmental Services TECHNICAL INFORMATION REPORT (TIR) WORKSHEET Part 1 PROJECT OWNER AND Part 2 PROJECT LOCATION AND • PROJECT ENGINEER DESCRIPTION Project Owner Mark Rousso Project Name Address 64 Rainier Avenue South, Suite"F," Rousso Short Plat"A" Renton, WA 98055 Location Phone Township 23 North Project Engineer Hal Grubb Range 5 East Company Barghausen Consulting Engineers, S.E. 1/4 Section 5 J Inc.

Project Description/Background The applicant, Marc Rousso, has proposed to subdivide a 0.40-acre parcel into three lots. The property is currently developed with an existing single family residential structure, which is proposed to remain on Lot 1 and an existing 160 square foot garage proposed to be removed or demolished as part of this application. In addition, a subterranean pool that straddles proposed Lots 2 and 3 would be demolished and filled prior to final short plat recording. Lots 2 and 3 are intended for the eventual development of a detached single family home. The lots are proposed at 5,655 square feet (Lot 1), 5,325 square feet (Lot 2) and 6,329 square feet (Lot 3) in size. The proposal for a total of three residential units on the site arrives at a density of 7.5 dwelling units per acre (du/ac). Lot 1 abuts Aberdeen Avenue NE and would be provided access from that street. A shared 20-foot wide private driveway easement located on the south side of the development is being proposed to provide access to Lots 2 and 3. The shared private driveway easement would have direct access to Aberdeen Avenue NE. • Lastly, the topography of the subject site is generally flat and the site is predominately vegetated with grass lawn and other ornamental vegetation and trees. No critical areas were found at the subject site during the review of this application. 2. Environmental Review Except when located on lands covered by water or sensitive areas, short plats are exempt from SEPA Environmental Review pursuant to WAC 197-11-800(6)(a). 3. Compliance with ERC Conditions N/A 4. Staff Review Comments Representatives from various city departments have reviewed the application materials to identify and address issues raised by the proposed development. These comments are contained in the official file, and the essence of the comments has been incorporated into the appropriate sections of this report and the Departmental Recommendation at the end of the report. 5. Consistency Short Plat Criteria Approval of a plat is based upon several factors. The following short plat criteria have been established to assist decision-makers in the review of the plat: a) Compliance with the Comprehensive Plan Designation The site is designated Residential Single Family(RSF)on the Comprehensive Plan Land Use Map. The RSF designation is intended to promote and enhance single family neighborhoods. The proposal is consistent with the RSF designation in that it would allow for the future construction of a single family home, thereby promoting goals of infill development. The proposal is consistent with the following Comprehensive Plan Land Use and Housing Element policies: Policy LU-34. Net development densities should fall within a range of 5 to 8 dwelling units per acre in Residential Single Family neighborhoods. shpltrpt.doc City of Renton P/B/PW Department Administrative Land Use Action REPORT AND DECISION DATED June 26,2001;PROJECT LUA-01-036,SHPL-A Page 4 • The net density of the proposed subdivision, 7.5 dwelling units per acre, is within the density range prescribed. Policy H-4. Encourage inlill development as a means to increase capacity. The proposal would create two additional lots, thereby increasing density within a currently developed residential area. b) Compliance with the Underlying Zoning Designation The subject site is designated Residential —8 Dwelling Units per Acre (R-8) on the City of Renton Zoning Map. The proposed development would allow for the future construction of up to two new single family dwelling units. The allowed density range in the R-8-zone is a minimum of 5.0 to a maximum of 8.0 dwelling units per acre. Net density is Calculated after the deduction of sensitive areas and areas intended for public right-of-way from the gross acreage of the site. The property does not contain any sensitive areas nor areas required for right-of-way dedication. The proposal for 3 units on the 0.40-acre site would arrive at a net density of 7.5 dwelling units per acre—within the allowed density range of the zone. The allowed building lot coverage in the R-8 zone is 35 percent or 2,500 square feet whichever is greater for lots over 5,000 square feet in size. Lot 1, with the existing residential structure, has a lot coverage of approximately 18 percent after the short plat,which is within the allowed range. Setbacks in the R-8 zone are as follows: front yard 20 feet, side yard 5 feet, side yard along a street 15 feet, and rear yard 20 feet. Upon recording of the short plat, the existing single family structure on Lot 1 would meet the minimum required setbacks as established by code. While no construction is planned for Lots 2 and 3 at this time, the lots appear to have adequate area to provide for a new single family residence while meeting the required setbacks and lot coverage. • In addition,each lot would have adequate area to provide two off-street parking spaces as required by the parking regulations. c) Compliance with Subdivision Regulations Streets:No new public streets would be created as part of the proposed short plat. RMC section 4-7-150.F of the Subdivision Regulations requires the installation of full street improvements, including curb, gutter, 6-foot sidewalk, and half-street pavement along the site's Aberdeen Avenue NE street frontage pursuant to City of Renton Street Standards (RMC section 4- 6-060), unless waived or deferred through the City of Renton Board of Public Works. On April 11, 2001 the City of Renton Board of Public Works deferred the required street improvements. The proposed subdivision is anticipated to generate additional traffic on the City's street system. In order to mitigate transportation impacts,a Transportation Mitigation Fee based on $75.00 per net new average daily trip attributed to the project will be required. The additional lots are expected to generate approximately 9.57 new average weekday trips per lot with credit given for the existing single family residence. The fee for the proposed short plat is estimated at$1435.50($75.00 x 9.57 trips x 2 =$1435.50)and is payable prior to the recording of the short plat. Blocks:No new blocks will be created as part of the proposed short plat. Lots: The minimum lot size permitted in the R-8 zone is 4,500 square feet. The proposed plat would create three lots—Lot 1 at 5,655 square feet, Lot 2 at 5,325 square feet and Lot 3 at 6,329 square feet. The proposed lot sizes are compatible with other existing lots in this area under the same R-8 zoning classification. The proposed lots also comply with the R-8 requirements for minimum lot width (60 feet for corner lots and 50 feet for interior lots)as well as minimum lot depth (65 feet). The residence proposed to remain on Lot 1 meets the required setbacks and lot coverage permitted in the R-8 zone. In • addition, proposed Lots 2 and 3(interior lots)appears to have adequate building area for the construction of a single family residence when taking setbacks and lot coverage requirements into consideration. shpltrpt.doc City of Renton P/B/PW Department Administrative Land Use Action REPORT AND DECISION DATED June 26,2001; PROJECT LUA-01-036,SHPL-A Page 5 The size, shape, orientation, and arrangement of the proposed lots comply with the requirements • of the Subdivision Regulations and the development standards of the R-8 zone. In addition, each lot would have access to a public street(Aberdeen Avenue NE). d) Reasonableness of Proposed Boundaries Access: Each lot will have direct access to a public right-of-way(Lot 1 direct street frontage from Aberdeen Avenue NE and Lots 2 and 3 from a shared private 20-foot wide access easement off Aberdeen Avenue NE). The proposed 20-foot private shared driveway easement would be located on the south side of the subject site. A shared private driveway may be permitted for access up to two lots that do not abut public right- of-way. In addition, the applicant requested a modification to eliminate the required emergency access turnaround because the beginnigg of the pipestem portion of Lot 3 is less than 150 feet in length from the edge of the Aberdeen' Xvenue NE right-of-way. The modification was granted By the City of Renton's Development Services Division on June 21, 2001; however,two conditions were placed on the modification approval. The first condition is the applicant shall post no parking signs on the shared 20-foot wide private driveway easement, and the second condition is the easement shall be 20 feet of paved surface subject to the City of Renton's Development Services Division. The above modification is attached as part of this staff report. This proposal does comply with the above-mentioned regulations as Lot 1 is abutting Aberdeen Avenue NE and the proposed shared private driveway easement would be 20 feet in width with a minimum of 20 feet of pavement as required by code and the above-mentioned modification request. Topography.The topography of the site gently slopes to the east, but is relatively flat. The property is vegetated with grass lawn and several ornamental and native trees. The development of the site will require the removal of several trees located on Lot 3 for the eventual development of a single family residence. Lastly, the short plat would involve minimal grade and fill activities • mainly associated with the filling of the subterranean pool straddling Lots 2 and 3. The proposed amount of grading activities is expected to be approximately 170 cubic feet,which will require a grading permit from the City's Development Services Division at the time of infrastructure installation. Relationship to Existing Uses:The properties surrounding the subject site are designated R-8 on the City's zoning map. The proposal is similar to existing development patterns in the area and is consistent with the Comprehensive Plan and Zoning Code,which encourage residential infill development. e) Availability and Impact on Public Services(Timeliness) Police and Fire: Police and Fire Prevention staff indicate that sufficient resources exist to furnish services to the proposed development, subject to the condition that the applicant provide Code required improvements and fees. A Fire Mitigation Fee, based on $488.00 per new single family lot with credit given to the existing single family residence, will be required in order to mitigate the proposal's potential impacts to emergency services. The fee is estimated at $976.00 and is payable prior to the recording Of the short plat. Recreation: The proposal does not provide on-site recreation areas for future residents of the proposed short plat. However, there are existing recreational facilities in the area such as: Gene Coulon Memorial Park, Sunset Court Park, and Kennydale Lions Park. Therefore, in order to offset recreational impacts associated with this development, a Park Mitigation Fee would be required. Specifically, a Parks Mitigation Fee of$530.76 per new single family lot will be required and is also payable prior to the recording of the short plat. Credit would be given to the existing single family residence. Schools: According to the Draft Environmental Impact Statement for the City of Renton Land Use Element (January 16, 1992), the City of Renton has a student generation factor of 0.44 students • per single family residential dwelling. Therefore, it is anticipated that the proposed short plat would result in 0.44 new children to the local schools (Kennydale Elementary School, McKnight Middle School, and Hazen High School). The Renton School District has indicated they can accommodate an additional 0.88 students generated by this proposal. shpltrpt.doc City of Renton P/B/PW Department Administrative Land Use Action REPORT AND DECISION DATED June 26,2001;PROJECT LUA-01-036,SHPL-A Page 6 • Storm Water. A 12-inch storm water pipe is located in Aberdeen Avenue NE. A drainage report was submitted with the application and has been reviewed by the City of Renton's Plan Review Section. A Surface Water System Development Charge of$525.00 per new single family lot would be collected as part of the construction permit or prior to the recording of the short plat. Water and Sanitary Sewer Utilities: There is an existing 16-inch water and 8-inch sewer main located in Aberdeen Avenue NE. No extensions will be required for this project. The applicant would, however, be required to make the necessary connections to serve future development on Lots 2 and 3. A Water System Development Charge of$1,105 per new single family lot, as well as a Sewer System Development Charge of$760.00 per new single family lot, would be collected as part of the construction permit or prior to the recording of the short plat.

Jordan SUBJECT: Rousso Short Plat A File No. LUA01-036,SHPL-A STREET IMPROVEMENT MODIFICATION REQUEST • The applicant has requested modification of the standard emergency vehicle turn around requirement for a proposed private 20-foot shared driveway serving Lot 2 and Lot 3 of the Rousso Short Plat A. • The applicant is proposing a 134-foot shared private driveway from Aberdeen Avenue NE to the beginning of the pipestem portion of Lot 3. However, the total distance to the closest • corner of the building envelope for Lot 3 is over 150 feet from the edge of pavement to the Aberdeen Avenue NE right-of-way,typically requiring an emergency turn around. • The applicant is proposing the installation of a shared private driveway a minimum of 20 feet in width. The shared private driveway from Aberdeen Avenue NE would extend to the beginning of the pipesteme portion of Lot 3. This would be less than 150 feet from the edge of the existing Aberdeen Avenue NE right-of-way. Therefore, the applicant is requesting a modification from the required emergency vehicle turn around due to Lot 3 being less than 150 feet from the public street. • It should be noted that other modifications from the standard street improvements adjacent to the plat have been requested and approved by the City of Renton Board of Public Works. Improvements that have been waived include the installation of curbs, gutters and sidewalks along the site's Aberdeen Avenue NE frontage. • Street improvement requirements for new plats can be modified by the City if there are practical difficulties in carrying out the provisions of the Street Improvement Ordinance. In order for a modification to be approved, the City must "find that a special individual reason makes the strict letter of this Ordinance impractical, that the modification is in conformity with the intent and purpose of this Ordinance, and that such modification: (1) Will meet the objectives of safety, function, environmental protection and maintainability intended by the requirements of this Ordinance, based upon sound engineering judgment, (2) Will not be injurious to other property(s)in the vicinity." • The shared private driveway as proposed, would serve Lots 2 and 3 and would be less than 150 feet in length. In the event that an emergency response vehicle is required within this short plat, the emergency response vehicle could stop at the end of the shared driveway and still serve the future single family residence to be located on Lot 3. Furthermore, because the shared driveway is less than 150 feet in length the emergency response vehicle could back • out the shared driveway onto Aberdeen Avenue NE. Lastly, the City of Renton Fire Rousso Short Plat A LUA01-036, SHPL-A • Prevention Bureau has indicated in writing that an emergency vehicle turn around would not be required per the Uniform Fire Code as part of this proposed short plat. • The proposed modification would eliminate the requirement for an emergency vehicle turn around. This can be accomplished because the shared private drive would be less than the minimum length (150 feet), which triggers an emergency vehicle turn around. The proposal would meet all the objectives of safety, function, environmental protection and maintainability intended for a private shared driveway, with the exception of providing for an emergency vehicle turn around. There are no indications that the elimination of emergency vehicle turn around would be injurious to other properties. • The modification is approved with the following-conditions: 1. The shared private driveway shall be a minimum of 20 feet in width and shall be paved subject to the City of Renton's Development Services Division. 2. The shared private driveway shall be signed for "No Parking" along both sides of the driveway. If the requested modification is approved as presented above,please sign and date below. 1 • ` 621101 Neil Watts, Development Services Director Date cc: yellow file • 3.0 OFF-SITE ANALYSIS 3.1 Preliminary Drainage Report
